FN9065.3

Single Event and Total Dose Hardened,

High-Speed, Dual Output PWMs

Features

• Electrically Screened to DSCC SMD # 5962-02511

• QML Qualified per MIL-PRF-38535 Requirements

The single event and total dose hardened IS-1825ASRH and

ISL71823ASRH pulse width modulators are designed to be

used in high frequency, switching power supplies in either

voltage or current-mode configurations. Both designs

include a precision voltage reference, a low power start-up

circuit, a high frequency oscillator, a wide-band error

amplifier and a fast current-limit comparator.

• Radiation Environment

- Total Dose. . . . . . . . . . . . . . . . . . . . . 300krad(SI) (max)

- Latch-up Immune . . . . . . . . . . . . . Dielectrically Isolated

- SEU immune . . . . . . . . . . LET = 35MeV/mg/cm (max)

• Oscillator Frequency . . . . . . . . . . . . . . . . . . . .1MHz(max)

• High Output Drive Current . . . . . . . . . . . . . . .1A peak(typ)

• Low Start-up Current . . . . . . . . . . . . . . . . . . . 300µA(max)

The IS-1825ASRH features dual, alternating outputs

operating from zero to less than 50% duty-cycle, while the

ISL71823ASRH features dual, in-phase outputs operating

from zero to less than 100% duty cycle.

• Undervoltage Lockout

- Start Threshold . . . . . . . . . . . . . . . . . . . . . . . .8.8V(max)

- Stop Threshold . . . . . . . . . . . . . . . . . . . . . . . . 7.6V(min)

- Hysteresis. . . . . . . . . . . . . . . . . . . . . . . . . . 300mV(min)

Constructed with the Intersil Rad-hard Silicon Gate (RSG)

dielectrically isolated BiCMOS process, these devices are

immune to single event latch-up and have been specifically

designed to provide a high level of immunity to single event

transients. All specified parameters are guaranteed and

tested for 300krad(Si) total dose performance.

• Improved Soft-Start Function Compared with Commercial

1825A/1823A Types

• Pulse-by-Pulse Current Limiting

Detailed Electrical Specifications for these devices are

contained in SMD 5962-02511. A “hot-link” is provided

on our website for downloading the SMD.

• Latched Overcurrent Comparator with Full Cycle Restart

• Programmable Leading Edge Blanking

Applications

• Voltage or Current-Mode Switching Power Supplies

• Control of High Current MOSFET Drivers

• Motor Speed and Direction Control
